Displaying Disk Label Information

Language:

To display disk label information, use the prtvtoc command.

# prtvtoc path/device-name

where device-name is the raw disk device in the patch that you want to examine.

Note - To use this command, you must have the appropriate administrative rights. Refer to Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

The information varies depending on the current label of the disk. On VTOC labeled disks, information about tracks and cylinders is included. On EFI labeled disk, no track or cylinder information is provided.
